Form in a painting is the element that lends it visual coherence, and can suggest motion, perspective, or repose as well as shape, whether it derives from combinations of simple triangles, circles, and squares, or complex arrangements of intersecting lines and overlapping irregular figures. This book analyzes examples of still life, portraits, figures, landscapes, water scenes, skies, and abstract paintings from such artists as Edvard Munch, Paul CÚzanne, Vincent van Gogh, Franz Marc, Leonardo da Vinci, Juan Gris, Egon Schiele, and Paul Klee, illuminating the fundamental shapes from which each painting is constructed.
